Question Help,pc randomly restarting Psu or gpu problem?

[Xero666]

So yesterday i encountered a problem on my custom build PC after a year usage without problem , which is My computer seem to restart randomly when playing games or in full load activity, ive been monitoring my temperature but i see a normal safe temperature (74 C max on cpu, 60 C max on gpu)

However whenever i installed an old graphics driver (or any nvidia gpu driver that's different from the one that restart my computer) the restarting didn't happen even when im playing games hours nonstop after that. But its been 2 or 3 weeks after that and it seems the problem occured again and then i installed a different driver again and it solved again. I also remembered this is starting to happen a week after i upgraded my cpu and changed my cpu fan. So what is wrong with my pc? Gpu or the Psu ?

My Spec:

The cpu fan is deepcool ck-11509
And my psu is still stock from the case (case and psu brand is spc i think it's chinese)

Sorry for my english, english is my 2nd language

Normally, when a PC restarts itself, it is mostly heat related, but could also be the PSU / power management related. Maybe your PSU cannot provide enough power.
What PSU do you have? Any way to figure that out? At least how much Watt output would help.

First place to check is usually temperature and power supply. You've eliminated temperature.

My next step would be to replace the power supply. Even if it doesn't fix the problem, I'd never run a PC with a dodgy Chinese power supply that appears (from what you said) to have come with a case. In any event, it's very difficult to diagnose issues like this when you have a garbage power supply in the mix.

That's all i can get from it. I cant even find any info in the internet.

So i should just change my power supply? Im concerned about the gpu because of that driver case where it solved with just changing another driver

If you change the video driver and it works, it is rarely a hardware issue with the GPU (not impossible, but improbable).
But yes, it is a 350 Watt PSU, which will most likely not be able to provide the amounts of power required everywhere at times. Keep in mind that the power usage of your components varies depending on their workload. So that might explain, why it can take a while for it to simply shut down, unless load is high.

I would test with a more powerful PSU (450 Watt and above) and check if that solves the issue.

Well for now i will update after i change my psu with a better one and see what happens and hope its not my gpu failing. This morning I didn't do games and the pc just restarted when i opened 15 or more tabs on firefox. Thanks for the reply

Do that. I assume your new CPU is a lot more power hungry than your old one. Quad cores tend to eat quite a bit.

Additionally you can also test, if one of your RAMs is maybe faulty, by booting the PC with each RAM single for testing. If it doesn't boot with one of them, then that one's dead.
